Non-blocking issues

[Swiddis]

Is there a reason we update _index to indicate it's unused, while using it in reducer?

[ps48]

The linter is not able to understand that index is used in reducer and leads to no-unused-vars error. So marked this one as an internal variable.

[Swiddis]

There's a lot of duplicated navigation logic here based on label text, that seems like something that's likely to break over time. Should there be a helper for this navigation, or a better selector?

[ps48]

I'll leave this one as is for now. I'm updating some of these with cypress.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/dashboards-observability/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/dashboards-observability/backport-2.x
# Create a new branch
git switch --create backport/backport-1307-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 de90b01508a39117f6aa9115c073eff8229c0f56
# Push it to GitHub
git push --set-upstream origin backport/backport-1307-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/dashboards-observability/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-1307-to-2.x.
